If you mean 7 = 7x-3 then the perpendicular slope is -1/7 and the equation is y = -1/7x
slope intercept form is y = mx + b where m=slope and b=y-interceptfirst solve the equation for y7x-5y=357x=5y+355y=7x-35y=7x/5-35/5y=(7/5)x-7so the slope is 7/5 and the y-intercept is -7
x=y7+2
the question does not make sense to make a graph; you need an equation, that means there must be an equals sign. (or an ordering, that means using a greater than sign like this > or a less than sign like this< )
7x + y + 3 = y7x + 3 = 07x = -3x = -3/7
